How to Install and Setting Apache, MySQL, PHP-FPM on Ubuntu 24.10

Building a dynamic website on Ubuntu 24.10 requires a robust web server, a reliable database, and a powerful scripting language. This guide will walk you through the process of installing and configuring Apache, MySQL, and PHP-FPM, the core components for hosting modern web applications, on your Ubuntu 24.10 server.

We'll cover the installation process from start to finish, ensuring your setup is secure and optimized for performance. Whether you're a seasoned developer or a curious beginner, this guide will provide the essential steps and knowledge to get your web environment up and running smoothly.

Step 1: A Foundation of Updates

Before embarking on any installation, it's crucial to ensure your system is running the latest software and security patches. This practice minimizes vulnerabilities and guarantees optimal performance.

Open your terminal and execute the following commands:

sudo apt update
sudo apt upgrade
    

These commands refresh the package list and upgrade existing software packages, respectively.

Step 2: The Powerhouse: Installing Apache

Apache, a widely used web server, forms the foundation of our web environment. Let's get it installed:

In your terminal, execute:

      sudo apt install apache2
    

This command will install Apache and its dependencies. Once the installation completes, start the Apache service with:

      sudo systemctl start apache2
    

To ensure Apache automatically starts on system boot, run:

      sudo systemctl enable apache2
    

Confirm your Apache installation by navigating to your server's IP address in your web browser. You should see the Apache default welcome page, indicating a successful installation.

Step 3: Fortifying Your Web Fortress: Securing Apache

Security is paramount in the digital world. We'll take steps to protect your Apache server from potential threats.

Disabling Directory Listings:

To prevent unintended directory listings, which could reveal sensitive information, edit the Apache configuration file:

      sudo nano /etc/apache2/apache2.conf
    

Locate the <Directory /var/www/> section and modify the Options line to:

      Options -Indexes +FollowSymLinks
    

Save the file (CTRL+X, Y, Enter) and restart Apache to apply the changes:

      sudo systemctl restart apache2
    

Hiding Version Information:

To further enhance security, we'll conceal Apache's version information:

      sudo nano /etc/apache2/conf-available/security.conf
    

Set the following options:

ServerTokens Prod
ServerSignature Off
    

Save the file and restart Apache again.

Step 4: The Data Vault: Installing MySQL

MySQL, a powerful database management system, will store your website's data. Let's get it installed:

      sudo apt install mysql-server
    

Upon successful installation, we'll secure the MySQL installation with the following command:

      sudo mysql_secure_installation
    

You'll be prompted to set a strong root password for your MySQL database. Follow the on-screen instructions to remove anonymous users, disable remote root login, and remove test databases.

To verify the installation, log in to the MySQL root account:

      sudo mysql -u root -p
    

Enter your root password when prompted. You can exit MySQL by typing:

      exit;
    

Step 5: Powering Up Your Scripts: Installing PHP and PHP-FPM

PHP-FPM (FastCGI Process Manager) significantly boosts the performance of PHP scripts when used with Apache. We'll install PHP and PHP-FPM using a PPA (Personal Package Archive) for the latest versions.

Add the PPA to your system:

sudo add-apt-repository ppa:ondrej/php
sudo apt update
    

Install PHP and PHP-FPM:

      sudo apt install php8.3 php8.3-fpm libapache2-mod-fcgid
    

(Note: At the time of writing, PHP 8.3 is the latest version. You can replace it with any newer version if necessary.)

Enable the necessary Apache modules for PHP-FPM:

sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php8.3-fpm
    

Finally, restart Apache to enable PHP-FPM:

      sudo systemctl restart apache2
    

Step 6: Testing PHP Integration

To confirm PHP is working seamlessly with Apache, we'll create a simple test file:

      sudo nano /var/www/html/info.php
    

Paste the following code into the file:

<?php
  phpinfo();
?>
    

Save the file (CTRL+X, Y, Enter) and navigate to http://your_server_ip/info.php in your web browser. You should see the PHP information page, indicating a successful PHP integration.

Remove the test file after confirmation to avoid exposing sensitive information:

      sudo rm /var/www/html/info.php
    

Step 7: Organizing Data: Configuring MySQL Databases

We'll now create a database and a user to manage your website's data:

Log in to MySQL as the root user:

      sudo mysql -u root -p
    

Create a new database:

      CREATE DATABASE your_database_name;
    

Replace your_database_name with your desired database name.

Create a new user with appropriate privileges:

CREATE USER 'your_username'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON your_database_name.* TO 'your_username'@'localhost';
FLUSH PRIVILEGES;
    

Replace your_username and your_password with your chosen username and password.

Exit MySQL:

      EXIT;
    

Step 8: Securing Your Gateway: Enabling the UFW Firewall

To protect your server from unauthorized access, we'll enable the UFW (Uncomplicated Firewall).

Enable UFW:

      sudo ufw enable
    

Allow essential services like OpenSSH for remote access and HTTP/HTTPS traffic for your web server:

sudo ufw allow OpenSSH
sudo ufw allow 'Apache Full'
    

Check UFW status to ensure it's active:

      sudo ufw status
    

Step 9: Advanced Apache Security (Optional but Recommended)

For heightened security, consider enabling the following Apache modules:

ModSecurity: A web application firewall for extra protection:

sudo apt install libapache2-mod-security2
sudo a2enmod security2
sudo systemctl restart apache2
    

SSL (for HTTPS): Secure your site with SSL using a free certificate from Let's Encrypt:

sudo apt install certbot python3-certbot-apache
sudo certbot --apache
    

Follow the prompts to install the SSL certificate.
